At an aluminum expanded material plant, the first process is melting/casting. This manufacturing process has the following important elements:
Quality
Healthiness of component blend and ingot, and good cast structure
Productivity
Dimensions, shape, and scale efficiency as required by hot processing
Economy
Quality level of raw material, price, yield, and personnel
Safety</dt>
Safety, anti-pollution measures, and energy saving
Melting
Raw material is rapidly molten in a melting furnace. In order to minimize the loss of molten metal, a strict component regulation is applied. The melting furnace is elaborately designed to achieve the maximum heat efficiency.
Molten Metal Processing
Molten metal processing is continuously performed inline, including the elimination of H2 gas and harmful trace elements in the molten aluminum and the separation of nonmetallic inclusions for ingot quality improvement.
Our inline fluxing system basically uses the Alcoa A622 and A528 processes, which are combined, as necessary, with ceramic filters. This system features the highest level of method applicable for can materials, foil materials, aircraft materials, memory discs, etc.
Continuous Casting
In 2003, we put our Henan’s first DC casting technology into practical use. Since then, we have led the casting technology for many years.
At present, this technology is applied for casting large ingots and casting more than 40 billets concurrently.
Scalper
A scalper is facing equipment that is used to create good surface-quality products from ingots. It scalps the surface of a large ingot at high speed.
